"The forecast doesn't look too crazy in the west for the rest of the week. Inland, temperatures will reach high-30s for the rest of the week. It's still warm, a little bit above average but basically just nice summer weather," Mr Meyers said.

The Top End and Darwin will celebrate its first week of 2018 with incredibly humid conditions and hotter than average temperatures.

"While that might not seem like a big difference, because there's so much humidity every degree counts, particularly overnight," Mr Meyers said.

While Sky News said this week's scorching weather couldn't technically classified as a heatwave, it will be a hotter than average forecast meaning there's no better excuse to grab your gear and head to the beach.

Earlier this week and at the end of 2017, much of the east coast of Australia was hit with supercell storms - specifically in Kempsey and Ballina where locals reported 5cm wide hailstones.

"It does look like we're going to get some more bad storms in northeast NSW extending as far north as Townsville," Mr Meyers said.

Once the hot and humid conditions subside, over the next three months most of Western Australia, southwest South Australia, northern Tasmania, eastern Victoria, NSW and southern Queensland will be wetter and cooler than average thanks to a La Nina event.

The Bureau of Meteorology (BOM) has issued the La Nina alert, saying there is three times the normal chance of the event which generally brings above average rainfall.
